Question 77796
If you want to find {{{a[10]}}}, then simply multiply r by {{{a[9]}}}. The reason why this works is because r is the constant that you multiply by to get from term to term. So we find that {{{a[10]}}} equals


{{{a[10]=a[9]*r}}} 


{{{a[10]=8*(0.5)}}} 


{{{a[10]=4}}}

So our tenth term is 4
